Rotation of web site content to prevent E-mail spam/phishing attacks

ABSTRACT

A method for phishing attack management through Web site content rotation includes receiving a request for a variation of a component to be incorporated into a Web page from a requesting Web page rendering engine from over a computer communications network. The method also includes comparing the requested variation of the component to a currently configured variation of the component. Finally, the method includes returning both the requested variation of the component and an alert indicating a possible phishing attack in response to the request if the requested variation of the component differs from the currently configured variation of the component.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to network security and more particularly to phishing attack management.

2. Description of the Related Art

The terms “phishing” and “brand spoofing” refer to the transmission of an e-mail to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft. In a phishing scam, an e-mail appearing to originate from the legitimate enterprise (whether by the inclusion of a well-known icon or logo, or domain name) directs the user to visit a Web site where the users will be asked to update personal information, such as a password, credit card number, social security number, or bank account number. The Web site, however, merely is an imposter site masquerading for the legitimate Web site for the legitimate enterprise. For the unsuspecting user, valuable confidential information will be revealed to the fraudster.

Government experts and technical experts alike recommend vigilance as a prime means of combatting the phishing scheme. Specifically, experts recommend that end users never reveal private information through a Web site in response to receiving an e-mail requesting the private information, no matter how legitimate the e-mail appears. Rather, experts encourage recipients of such e-mails to directly phone the legitimate enterprise through a previously known telephone number to inquire as to the legitimacy of the e-mail. Even still, many users simply lapse in caution and unwittingly participate as victims in the phishing scam.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art in respect to phishing attack management and provide a novel and non-obvious method, system and computer program product for phishing attack management through Web site content rotation. In an embodiment of the invention, a method for phishing attack management through Web site content rotation is provided. The method includes receiving a request from over a computer communications network for a variation of a component to be incorporated into Web page content from a requesting Web page rendering engine such as a Web browser or e-mail client configured to render Web page content. The method also includes comparing the requested variation of the component to a currently configured variation of the component. Finally, the method includes returning both the requested variation of the component and an alert indicating a possible phishing attack in response to the request if the requested variation of the component differs from the currently configured variation of the component.

In one aspect of the embodiment, comparing the requested variation of the component to a currently configured variation of the component includes comparing a uniform resource locator (URL) of the requested variation of the component to a URL of the currently configured variation of the component. In another aspect of the embodiment, returning both the requested variation of the component and an alert indicating a possible phishing attack in response to the request if the requested variation of the component differs from the currently configured variation of the component, includes returning both the requested variation of the component and a visual alert superimposed over the requested variation of the component indicating a possible phishing attack in response to the request if the requested variation of the component differs from the currently configured variation of the component.

Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:

FIG. 1 is a pictorial illustration of a process for phishing attack management through Web site content rotation;

FIG. 2 is a schematic illustration of a Web site content data processing system configured for phishing attack management through content rotation; and,

FIG. 3 is a flow chart illustrating a process for phishing attack management through Web site content rotation.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for phishing attack management through Web site content rotation. In accordance with an embodiment of the invention, a set of different variations of a Web site component of a page of a Web site can be provided and the page of the Web site can be configured to retrieve and incorporate only a single one of the variations of the Web site component. Periodically, the page of the configuration of the page of the Web site can be updated to retrieve and incorporate a different one of the variations of the Web site component from the set. Responsive to receiving a request for the Web site component from a page of the Web site that specifies the retrieval and incorporation of a variation of the Web site component, yet that differs from a variation of the Web site component specified by the configuration of the page of the Web site, a warning message can be provided in association with the page of the Web site. In this way, a viewer of the page of Web site can be alerted to a potential phishing attack.

In further illustration, FIG. 1 pictorially shows a process for phishing attack management through Web site content rotation. As shown in FIG. 1, a Web page 140 of a Web site can be provided. One of different variations 120 of a component can be incorporated into the Web page 140, for example a menu bar or tool bar. Different ones of the variations 120 of the component can be incorporated into the Web page 140, but only one of the variations 120 of the component can be incorporated into the Web page 140 at any one time. A configuration 130 for the Web page 140 can be maintained to indicate the one of the variations 120 of the component incorporated into the Web page 140 at any one time, and can be maintained, for example, by way of a URL of the one of the variations 120 of the component incorporated into the Web page 140.

A Web server 110 can receive a request 160 for the delivery of one of the variations 120 of the component in connection with the rendering of a form 170 of the Web page 140 by a rendering engine such as that found in an e-mail client or Web browser in a client computing device 150. Phishing management 300 process can compare the request 160 for the delivery of one of the variations 120 of the component with the configuration 130 to determine if the currently selected one of the variations 120 of the component is the same as the requested one of the variations 120. If not, the requested one of the variations 120 can be served in response to the request 160 to the client computing device 150 with an alert 180 for inclusion in the form 170 of the Web page 140 indicating the possibility that a phishing attack has occurred.

The process described in connection with FIG. 1 can be implemented in a Web site content data processing system. To that end, FIG. 2 is a schematic illustration of a Web site content data processing system configured for phishing attack management through content rotation. The system can include a host computer 240 with at least one processor and memory configured for communicative coupling to different client computers 210 over a computer communications network 230, each of the client computers 210 being configured with a Web browser 220. The host computer 240 can include a Web server 250 serving different Web pages 290 to requesting ones of the Web browsers 220.

One of the pages 290 can incorporate a variation amongst multiple different variations of a component 270, such as a tool bar or menu bar. A current configuration 280 for the one of the pages 290 can indicate which of the variations of the components 270 is to be incorporated with every service of the one of the pages 290 to a requesting one of the Web browsers 220. Of import, phishing attack management module 260 can execute in the memory of the host computer 240. The module 260 can include program code enabled to compare a request for one of the variations of the component 270 for the one of the pages 290 to a variation of the component 270 set forth in the current configuration 280 for the one of the pages 290. In response to a dis-favorable comparison, the program code of the module 260 can be enabled to return an alert in conjunction with the requested one of the variations of the component 270 that the one of the pages 290 possibly represents a phishing attack.

Alternatively, the phishing attack management module 260 can include program code enabled to periodically change a reference in the one of the pages 290, such as an embedded file name, to a valid variation of the component 270 while superimposing upon or otherwise modifying other variations of the component 270 to include the alert. In this way, a contemporaneous request to the one of the pages 290 always will return the correct variation of the component 270 without the alert, but a version of the one of the pages 290 that is outdated and includes a reference to the incorrect variation of the component will return the alert indicating that the one of the pages 290 possibly represents a phishing attack without requiring the maintenance of a current configuration 280 for the one of the pages 290.

In even yet further illustration of the operation of the phishing attack management module 260, FIG. 3 is a flow chart illustrating a process for phishing attack management through Web site content rotation. Beginning in block 310, a component request can be received for a corresponding Web page. In block 320, a configuration for the corresponding Web page can be read to identify a currently incorporated variation of the component. In block 330 the currently incorporated variation of the component can be compared to the requested component—for instance by comparing the URL for each. In decision block 340, if the currently incorporated variation of the component matches the requested component, in block 350 the requested variation of the component can be returned to the requesting process. However, in decision block 340, if the currently incorporated variation of the component does not match the requested component, in block 360 the requested variation of the component can be returned to the requesting process along with an alert indicating a possibility that a phishing attack has occurred.
